Need to fasten a wooden leg to a metal bracket? Or attach a wood panel to a steel frame? Regular screws won't work ā you need a dual thread dowel screw (also called a hanger bolt). One end has a coarse wood thread that bites into timber; the other end has a standard machine thread that screws into a pre-tapped metal hole or a nut. These M6, M8, and M10 carbon steel hanger bolts are grade 4.8 strength with a color zinc finish. They're perfect for furniture assembly, machinery mounting, or any project that calls for joining wood to metal without exposed hardware. No more complicated brackets or messy adhesives ā just drill, thread, and tighten.
Dual thread design ā wood on one end, machine thread on the other ā The coarse, self-tapping wood screw end grips securely into lumber, plywood, or particle board. The machine thread end fits standard metric nuts or tapped holes in metal.
Available in M6, M8, and M10 diameters ā Choose the right size for your load requirements. M6 for light-duty furniture, M8 for general joining, M10 for heavy structural connections.
Grade 4.8 carbon steel construction ā Provides good tensile strength for most indoor and protected outdoor applications. Strong enough for bed frames, table legs, and machinery feet.
Color zinc finish for corrosion resistance ā The galvanized coating helps resist rust and tarnish. While not as robust as stainless steel, it's perfectly fine for indoor use or covered outdoor areas (porches, workshops, garages).
Works as a hidden fastener ā Once installed, the dowel screw is completely invisible. Your project looks clean and professional ā no screw heads showing on the surface.
